Performance Characteristics of Bifacial Dye-Sensitized Solar Cells with a V-Shaped Low-Concentrating Light System

Dye-sensitized solar cells (DSSCs) are attractive due to their simple fabrication process, low cost, performance stability, and eco-friendly characteristics. The power output (P-out) can be improved by applying an external concentrator, but this is rarely applied because of increasing temperature. Here, we successfully increased the P-out of bifacial DSSCs with the V-shaped plane, and concave mirrors showed an improved power output (P-out: 6.42 and 24.31 mW/cm(2), separately) compared to ones without mirrors (4.25 mW/cm(2)). The high surface temperature on the concave mirror can be reduced with 1 cm mirror distancing followed by a reduction in P-out (19.07 mW/cm(2)).

Automated summary

By utilizing a V-shaped plane and concave mirrors, the power output of bifacial DSSCs was successfully increased. However, the high surface temperature on the concave mirror could be reduced by placing the mirror 1 cm away, which also resulted in a decrease in power output.
